With high-purity ethylene as the main raw material, propylene, 1-butene, etc. as the copolymer monomer, and hexane as the solvent, the polymerization is carried out under low-pressure conditions of about 78℃~85℃ and 0.13MPa~0.70MPa using a highly active catalyst, and then dried, mixed, extruded, granulated, sieved, and homogenized to obtain polyethylene particles with a density of 0.940g/cm3~0.970g/cm3.
Frequently Asked Questions
High Density Polyethylene DGDB2480HDMDB2480
High Density Polyethylene (HDPE) grades DGDB2480 and HDMDB2480 are specific formulations of HDPE that are commonly used in various applications. Here is some general information about HDPE and its properties:
HDPE is a thermoplastic polymer known for its high strength, durability, and resistance to chemicals, moisture, and UV radiation. It has a high density compared to other polyethylene grades, which contributes to its excellent stiffness and tensile strength.
The specific properties and applications of HDPE grades, such as DGDB2480 and HDMDB2480, may vary based on the manufacturer or supplier. However, here are some common applications where HDPE is used:
1. Pipes and Fittings: HDPE pipes and fittings are widely used in water supply systems, gas distribution networks, and industrial piping systems. HDPE pipes offer excellent resistance to corrosion, abrasion, and chemicals, making them suitable for demanding applications.
2. Rotational Molding: HDPE is commonly used in the rotational molding process to produce large and complex hollow plastic parts such as tanks, containers, playground equipment, and automotive components.
3. Packaging: HDPE is utilized in various packaging applications, including bottles, containers, and caps. It offers good impact resistance and can be molded into different shapes and sizes.
4. Geomembranes: HDPE geomembranes are employed in environmental containment systems, such as landfills, mining ponds, and agricultural ponds. They provide a barrier against seepage and help prevent contamination of soil and water.
5. Construction: HDPE is used in construction applications such as underground electrical conduits, insulation for cables, and geomembranes for waterproofing.
6. Agricultural Applications: HDPE pipes and films are commonly used in agricultural irrigation systems, greenhouse structures, and lining systems for ponds and reservoirs.
